Dog Heatwave Safety: When Is It Too Hot to Walk Your Dog in the UK?
The UK is experiencing unusually high temperatures this spring and early summer, with parts of the country recently reaching over 34°C. Veterinary organisations and animal charities are now warning dog owners about a sharp rise in heat-related illnesses and emergency vet visits.
For many dogs, especially flat-faced breeds, older pets, overweight dogs, and thick-coated breeds, even a normal walk can become dangerous surprisingly quickly.
If you own a dog, understanding heatwave safety could genuinely save your pet’s life this summer.
What Temperature Is Too Hot to Walk a Dog?
Most UK vets recommend exercising caution once temperatures rise above 20–23°C, with serious risk beginning around 25°C and above.
Dogs cool themselves mainly through panting, which is far less efficient than human sweating. During hot weather, even moderate exercise can push their body temperature into dangerous territory.
According to veterinary guidance, the highest-risk conditions include:
- Midday or afternoon walks
- Humid weather
- Hot pavements or artificial grass
- Poor airflow
- Car journeys before or after walks
Many experts are now encouraging owners to adopt “Dogs at Dawn” or “Dogs at Dusk” routines during heatwaves.
The 7-Second Pavement Test
One of the most widely shared heatwave safety tips this year is the “7-second test.”
Simply place the back of your hand on the pavement for seven seconds. If it feels too hot for your skin, it is too hot for your dog’s paws.
Hot pavements can cause painful burns and blistering, particularly in smaller breeds or dogs that spend most of their time indoors.
Grass, woodland trails, and shaded areas are usually much safer alternatives during summer weather.
Dog Breeds Most at Risk During Heatwaves
Some breeds struggle far more in warm temperatures than others.
Veterinary experts warn that brachycephalic (flat-faced) breeds are particularly vulnerable because their shorter airways make cooling harder.
Higher-risk dogs include:
- French Bulldogs
- Pugs
- Bulldogs
- Boston Terriers
- Chow Chows
- Golden Retrievers
- Saint Bernards
- Great Danes
Older dogs, overweight pets, and dogs with breathing or heart conditions are also at elevated risk.
Signs of Heatstroke in Dogs
Heatstroke can escalate very quickly and should always be treated as an emergency.
Common warning signs include:
- Heavy panting
- Excessive drooling
- Weakness or lethargy
- Vomiting or diarrhoea
- Loss of coordination
- Bright red gums
- Collapse or seizures
Veterinary groups report that heatstroke cases rise dramatically during UK heatwaves, with some studies showing a fivefold increase during extreme weather periods.
How to Keep Your Dog Cool During Hot Weather
There are several simple ways to reduce the risk of overheating:
Walk Earlier or Later
Aim for early morning or late evening walks when temperatures are lower.
Provide Constant Fresh Water
Add extra water bowls around the home and garden during hotter days.
Use Cooling Treats
Many owners now use frozen treats, ice cubes, or frozen lick mats to help keep dogs cool.
Avoid Cars Completely
Even with windows open, temperatures inside vehicles can rise dangerously fast.
Create Cool Indoor Spaces
Tile floors, shaded rooms, fans, and cooling mats can all help reduce overheating.
Tick Season Is Also Increasing
Hotter weather does not just increase heatstroke risk. Tick activity is also rising across the UK, particularly in woodland, long grass, and parkland areas.
Ticks can carry diseases including Lyme disease, making post-walk checks especially important during summer months.
Check your dog carefully around:
- Ears
- Neck
- Toes
- Groin
- Under collars
Final Thoughts
Dogs rely entirely on us to make safe decisions for them during extreme weather.
Missing a walk for one day is far safer than risking heatstroke, dehydration, or burned paws. This summer’s heatwaves are already leading to increased veterinary warnings across the UK, and awareness among owners has never been more important.
With a few simple adjustments, you can keep your dog safe, comfortable, and healthy throughout the warmer months.
